So can I play EUIV or CK2 MP with no lag issues?

I'm not sure how much ping itself impacts those games, but I suspect it's less important than simple bandwidth. The games have an adjustable speed, and MP is generally played by setting the speed to a low level (typically in the range of 1 to 3). If one person is lagging behind, the game will automatically slow itself down to compensate. A ping of 140-160 I doubt would impact EU4/CK2 very much. On Mobius, we play EU4 MP games with people on both sides of the Atlantic and usually don't have many problems.
